Answer:
20 ft by 60 ft
Step-by-step explanation:
"What should the dimensions of the garden be to maximize this area?"
If y is the length of the garden, parallel to the stream, and x is the width of the garden, then the amount of fencing is:
120 = 3x + y
And the area is:
A = xy
Use substitution:
A = x (120 − 3x)
A = -3x² + 120x
This is a downward facing parabola. The maximum is at the vertex, which we can find using x = -b/(2a).
x = -120 / (2 · -3)
x = 20
When x = 20, y = 60. So the garden should be 20 ft by 60 ft.
Answer:
4
Step-by-step explanation:
8% is also 8/100. This would be true for all percents 0 to 100%. If it were 42% it can be written as 42/100.
So, 8% is 8/100. If you want to find 8/100 of 50 multiply them.
8/100 * 50/1 = (8*50) /100
400/100 = 4
